What iPhone hotspot does and how to turn it on
Your iPhone can share its cellular data with other devices — phones, tablets, laptops — through a feature called Personal Hotspot. When you turn it on, your iPhone becomes a small wireless router that broadcasts a network other devices can join. This uses your phone's data plan, so the data counts toward your monthly limit just as if you were using it on the iPhone itself.
To turn on Personal Hotspot, open Settings on your iPhone, tap Cellular, then tap Personal Hotspot. Toggle the switch to on. Your iPhone will show you a Wi-Fi password — this is what other devices need to connect. If you don't see Personal Hotspot in Settings, contact your carrier; some plans don't include it, though most do.
Once it's on, your iPhone stays on and in range for other devices to use it. If your phone locks or you walk away, the connection stays active — you don't have to keep the Settings screen open. Other devices will see your iPhone's name in their available Wi-Fi networks and can connect as long as they have the password.
Key Takeaways
- Personal Hotspot is found in Settings > Cellular > Personal Hotspot and broadcasts a Wi-Fi network that uses your phone's data plan.
- Other devices connect by finding your iPhone's network name in their Wi-Fi list and entering the password shown in your hotspot settings.
- Your iPhone must stay powered on and within range, but the screen can lock — the hotspot keeps working in the background.
- Data used through hotspot counts toward your monthly cellular limit, the same as data used directly on your phone.
- If Personal Hotspot doesn't appear in your Settings, your carrier may not include it on your plan, and you'll need to contact them to add it.
Connecting a second phone or tablet to your hotspot
On the device you want to connect, go to Settings and open Wi-Fi. You'll see a list of available networks. Look for your iPhone's name — by default it's something like "Marcus's iPhone" but you can change it in Personal Hotspot settings if you want. Tap the network name.
A password field will appear. Enter the password shown in your iPhone's Personal Hotspot settings. The device will connect and show a blue Wi-Fi icon next to your iPhone's network name. From that point on, the device will remember this network and reconnect automatically when your hotspot is on and in range.
You can connect multiple devices at once — typically up to five, though this varies by carrier and plan. Each one uses data from your iPhone's plan. If you're streaming video or downloading files on multiple devices simultaneously, your data will drain faster than if only one device is using it.
Connecting a laptop or computer to your hotspot
On Windows, open Settings, go to Network & Internet, then Wi-Fi. Click "Show available networks" and look for your iPhone's name in the list. Click it, then click Connect. When prompted, enter the password from your iPhone's Personal Hotspot settings. Windows will remember the network and reconnect automatically in the future.
On Mac, click the Wi-Fi icon in the top-right corner of the screen. Find your iPhone's network name and click it. A password box will appear — enter the password from your iPhone's hotspot settings. Your Mac will connect and show the Wi-Fi icon as filled in. Like Windows, your Mac will remember this network.
Once connected, your laptop or computer uses the internet exactly as it would on any other Wi-Fi network. All data goes through your iPhone's cellular plan. This is useful for checking email or browsing on a computer when you don't have access to a wired connection, but streaming video or large downloads will use data quickly.
Troubleshooting when devices won't connect
If a device can't find your iPhone's network, first check that Personal Hotspot is actually on — go back to Settings > Cellular > Personal Hotspot and confirm the toggle is switched on. Also make sure your iPhone has cellular signal; if you have no bars, the hotspot won't broadcast.
If the device sees the network but won't connect, the password is usually wrong. Double-check that you're entering it exactly as shown in your iPhone's hotspot settings — passwords are case-sensitive, and it's straightforward to misread a number or letter. If you're unsure, you can change the password in Personal Hotspot settings and try again with the new one.
If your iPhone shows Personal Hotspot is on but other devices still can't see the network, try turning the hotspot off and back on. Wait a few seconds between each step. If that doesn't work, restart your iPhone. These steps clear temporary glitches that sometimes prevent the network from broadcasting properly.
Managing data use when hotspot is active
Every megabyte used through your hotspot counts against your monthly data limit. Video streaming, app updates, and large file downloads use data much faster than email or web browsing. If you're on a limited plan, be aware of what devices are doing while connected.
You can see how much data your hotspot has used by going to Settings > Cellular > Cellular Data, then scrolling down to find Personal Hotspot. This shows you the total since your last reset. To reset the counter, go to Settings > General > Transfer or Reset > Reset Statistics. This doesn't affect your actual data usage — it just clears the counter so you can track a new period.
If you want to prevent accidental data drain, turn off Personal Hotspot when you're not actively using it. The toggle in Settings > Cellular > Personal Hotspot turns it off completely. Devices that were connected will lose internet access, but they'll reconnect automatically the next time you turn the hotspot back on.
When hotspot is slower than expected
Hotspot speed depends on your iPhone's cellular signal. If you're in an area with weak signal, your hotspot will be slow. Move closer to a window or to higher ground if possible — cellular signal often improves with a clearer line of sight to the cell tower.
If multiple devices are connected and using data at the same time, each one shares the available speed. If one device is downloading a large file or streaming video, other devices will feel slower. Disconnect devices you're not actively using to free up bandwidth for the ones you need.
Your carrier may also throttle hotspot speeds if you've used a very large amount of data in a month. Check your plan's terms or contact your carrier if you think this is happening. Some plans have separate hotspot data limits that are lower than your phone's data limit — if you hit that limit, hotspot will stop working even if you have phone data remaining.
Switching between Wi-Fi and hotspot on your iPhone
Your iPhone can use Wi-Fi for its own internet while also sharing hotspot to other devices. If you're at home with Wi-Fi, you can turn on Personal Hotspot and let other devices use your hotspot while your iPhone uses your home Wi-Fi. This saves your cellular data.
To do this, make sure your iPhone is connected to Wi-Fi first — go to Settings > Wi-Fi and join your home network. Then go to Settings > Cellular > Personal Hotspot and turn it on. Your iPhone will now use Wi-Fi for itself and broadcast hotspot to other devices using your cellular connection. This is a good way to share internet with guests without giving them your Wi-Fi password.
If you're not on Wi-Fi, your iPhone uses its cellular data for both its own use and for hotspot. There's no way to separate them — all data comes from the same plan. In this case, every device connected to your hotspot is drawing from your monthly limit.
Frequently Asked Questions
Does using hotspot drain my iPhone battery faster?
Yes. Broadcasting a Wi-Fi network and managing connections uses more power than normal phone use. If you're using hotspot for an extended time, plug your iPhone into power if you can. If you can't, turn off hotspot when you're not actively using it to preserve battery.
Can I use hotspot if I don't have unlimited data?
Yes, but data used through hotspot counts toward your monthly limit just like any other data. If you have a 5 GB plan and use 2 GB through hotspot, you have 3 GB left for your phone. Check your plan's terms to see if there are separate hotspot limits.
What's the difference between hotspot and tethering?
Hotspot and tethering are the same thing — hotspot is Apple's name for the feature. Some carriers or older devices use the term tethering, but they work the same way: your phone shares its cellular data with other devices.
Can I use hotspot on an older iPhone?
Most iPhones from the last ten years support Personal Hotspot. If you have an older model, check Settings > Cellular to see if the option appears. If it doesn't, your phone may be too old or your carrier may not support it on your plan.
What happens if I go over my data limit while using hotspot?
This depends on your plan. Some carriers slow your speed, some charge overage fees, and some cut off data entirely until your next billing cycle. Check your plan's terms or contact your carrier to understand what happens if you exceed your limit.
